Le Mans preparations continue, despite the event still being over 5 months away! I thought the whole experience was amazing when I last went in 2011, and vowed to do it bigger and better next time! Taking the caravan in 2014 will give us a huge amount of comfort compared to using a tent, and as I have said in numerous previous posts, I plan to provide us with satellite TV to watch the race from camp, as well as all sorts of other comforts such as a couple of gas fridges to cool beer, and 240v power (for the TV and satellite kit). (and of course a hot shower, toilet, gas BBQ, stove, hot water, and all the usual caravan goodies!)
As there is no electric hookup in the camping area we are staying on, We will need to run the caravan systems (water, lights, fridges etc.) on gas and 12v. I will also have 240v available via my home-brew power pack. As we are in France for 5 nights, we need a few batteries for contingency. Should the caravan battery go flat, I will need a spare, and should the battery in the power pack go flat, that too will need a spare. Charging mobile phones etc will demand an amount of power during the event, so I plan to use a dedicated battery for this, to preserve both the caravan battery, and the battery in the power pack.
To facilitate all of this, I have obtained a second high power car battery. I got my hands on a Bosch 100ah battery today, which is currently undergoing a maintenance charge. The other spare is from my BMW, as I replaced the battery a few months ago. Ordinarily, you would want a dedicated deep cycle leisure battery for a caravan (and my power pack as a leisure battery in it too) but car batteries will do just fine as backups. These batteries are past their best, but I expect that they will still serve us well, should we need to rely on them. After all, I don’t plan to take a generator.
With these x2 spares, the primary caravan battery, and my power pack, we should be well covered!
